Holy boobies!

Katlyn
I'm only 5 weeks and my boobs have grown SO much already. I have a really flat chest normally, but right now they're spilling out of the 36B bra I have (Still small, I know, but to me and my boyfriend they're massive 😂) How big do boobs normally get during pregnancy? I heard only a cup size, but I feel like mine are going to grow way more 😳
